I have a flock of chickens right now, but I'm interested in replacing a few chickens with guinea hens. Someone in the family has a chicken egg allergy (such bad luck!), but thus far guinea eggs are just fine. My chickens aren't free range -- they are confined to a run that's about 140 square feet. Thus far, everything I've seen about guinea hens describes free ranging. Is this because guinea hens need to free range, or would they be okay in a run setup? I've also seen that guinea hens are much louder than chickens. Are we talking about all-day vocalization? Are their calls just louder? More frequent? More unpleasant? Since we have neighbors (who are fine with chickens, but idk about guinea hens...), I don't want to annoy them too much. Thanks for any info!
